Yellowing leaves on very tall plants

    My plants are in the early stages of flowering. The tallest one is 7' 8". Over the past week the bottom leaves have been yellowing. I heard this is common late in flower, but these are not late in flower. I have been giving them tiger bloom once a week. Nute problem or maybe not enough light getting to the bottom? Maybe a gnat problem? This is my first outdoor grow and second grow overall.

    Old leaves turn yellow and die.
    You should pick them off because they will attract bugs. Those darker parts on the yellow leaves aren't good either. Indicate pathogens. Dying yellow leaves are often where pests and diseases enter the plants.
